ATTORNEY Patented July 16, 1940 UNITED STATES 'ATENT OFFECE y 2 Claims.

My invention relates to an improvement in the construction of shoes and particularly to soles of shoes and has among its objects and purposes to provide:

. A soft flexible sole for foot wear.

A sole having a iibrous insert.

An upper and lining having a strip extension to draw and secure the upper and lining to the sole.

A comfortable and durable shoe.

An outer sole surrounding the bottom, sides and top edges of the mid-sole.

I accomplish these and other objects by the construction herein described and shown in the K accompanying drawing forming a part hereof in which:

Fig. 1 is a plan View of my shoe with the upper and lining cut away.

Fig. 2 is a perspective view of my shoe.

Fig. 3 is a section at 3, Fig. 1.

Fig. 4 is a section at 4, Fig. 1.

Similar reference characters refer to similarparts throughout the several views of the drawing and in the specications to follow.

5 The construction of shoes and particularly ladies shoes with a view to greater neatness and comfort are made with soles of fabric and other materials at a sacrifice to durability. My invention, however, combines leather and other material and by the construction makes a durable shoe as well as one with the qualities of wearing comfort.

For the purpose of clarity and brevity, I have herein described and shown in detail one of the 35 embodiments of my invention which may be modified in numerous ways to suit the various uses to which it is suitable as will be apparent to one skilled in the art of manufacturing shoes after a study of the disclosure of my invention.

Referring to the drawing, the outer sole I is skived at its edges 2 and turned upwardly and around and over upon the mid-sole 3 to which it is joined in any well known manner as by cementing.

The upper 4 and lining 5 are secured by zigzag stitching 6 to the skived strip 'I which thus is extended beyond the lower edge of the upper and lining, drawn under and around the edge of the inner lsole 9 and over the skived edge 2 of the 50 outer sole I to which it is cemented.

The inner sole 9 is cut out at the ball of the foot along the line II andthe felt or fabric insert I2 is cemented at its edges to the edges on the line II of the cut out. The insert may be shaped or 6b eut out with the same die or otherwise to conform in outline to the line II of the cut out of the inner sole.

The mid-sole 3 is also preferably cut out along the line I4 which extends from the toe I 5 to heel I5 and is thus larger in area than the cut out of 5 the inner sole. I do not wish it understood that the insert II of the mid-sole, which also is cemented to mid-sole 3 along the line I 4, is always used as the `mid-sole; in some cases it may be solid or not cut out when the inner sole is softened by its insert of fibrous material.

By providing one of the soles, the inner sole for instance, with an insert, the softness and flexibility of the sole is increased. Likewise, when the mid-sole is cut out and an insert of brous material used, much greater softness and flexibility is provided. Also if but one or the other of the soles is cut out. a varying degree of softness and flexibility may be had and a still .greater degree of softness and flexibility or pliability may be had when both insole and mid-soleV are so cut out and lled with their inserts.

It will be seen therefore that the desired degree e of softness and pliability may be had by the construction of my shoe and its soles by combining the inner sole and mid-sole according to the cut outs selected.

The inner sole 9 may be covered in the usual manner by the sock lining I8.

The outer sole I and the mid-sole which it covers may be terminated at I9 near and over the front edge 2) of the heel 2| and the heel may be padded in the usual manner between the sock lining and the inner sole.

While I have described in detail one of the embodiments of my invention I do not wish to be limited to this detailed construction as ,it may be modied in many respects within the scope of the appended claims which set forth my 'invention.

I claim: E

l.. A shoe of the character described, an inner sole, an upper and a combination outer sole, said combination outer sole comprising an intermediate sole, a cut out in said intermediate sole leaving a completely closed frame, a filler of cushioning material. replacing the cut out portion, an exn terior sole of wear resisting material covering the intermediate sole and being turned up over the edges thereof, the overlapping margins of the exterior sole being joined to the frame of the intermediate sole, said upper being joined to the inner sole and to the combination outer sole.

2. A shoe of the character described, an inner sole, formed of a closed frame of wear resisting 55 intermediate sole and being turned up over the edges thereof, the overlapping margins of the exterior sole being joined to the frame of the intermediate sole, and an upper being joined to the inner sole and to the combination outer sole. 5
